The embodiment of the invention provides a scene description file analysis method and device, and relates to the technical field of video processing. Comprising the following steps: determining the type of each touch material attribute carried by each three-dimensional grid in a three-dimensional scene to be rendered according to a scene description file; when the type of a first tactile material attribute carried by a target three-dimensional grid in the three-dimensional scene to be rendered is a reference, obtaining an index value of an accessor index syntax element declaration in a dynamic picture expert group (MPEG) tactile texture of a target texture description module; the target texture description module is a texture description module corresponding to the first tactile material attribute, and obtains description information of a tactile media accessor for accessing decoded data of the target tactile media file according to an index value declared by the accessor index syntax element, the target tact
